LOCKING-RING.

Specification of Letters Patent.

Patented Nov. a, 1913.

Application filed July 14, 1911. Serial No. 638,488.

T 0 all whom it may concern Be it known that I, IVALTER L. KELLEY, acitizen of the United States, residing at Pawtucket, in the county ofProvidence and State of Rhode Island, have invented certain new anduseful Improvements in Looking-Rings, of which the following is aspecification.

.My invention relates to locking rings for tires and has for itsessential objects security in position and facility for application andremoval.

To the above ends essentially my invention consists in the novelconstruction, arran ement, and combination of parts here ina terdescribed, and illustrated in the accompanying drawings, wherein Figure1 represents in side elevation a wheel equipped withmy novel device,Fig. '2, a section on line 00 w of Fig. 1, Fig. 3, a side elevation,partially in transverse section, of a portion of the tire and adjacentparts, Fig. 4, a side elevation of the same showing the lockin ringelevated, Fig. 5, a side elevation of t e adjacent ends of the lockingring, Figs. 6 and 7,-side and end elevations respectively of the 'plateand at tached elevating screw, andFig. 8, a partial section on line a: wof Fig. 1 showing the locking ring at the instant of disengagement.

In the accompanying drawings like refcharacters. indicate like 'partsthroughout the Views.

My invention is shown in connection with a wheel 1 having the usualfelly 2 uponwhich is a rim body 3 constitutingthe tire seat and providedwith a laterally, extending annular concaved flange 5 upon one marginconstituting a ring seat, and provided upon its other margin preferablywith an annular raised flange or head 6. Any preferred usual form. ofwearing shoe or cover 8 is adapted to rest upon the tire seat 3 and maybe retained thereon by any desired means. In the present instance theretain? ing meansconsists of two bearing rings 11 and 12 of similarconstruction seated upon the rim 3 upon either side of the tire cover;

and provided respectively with outwardly inclined outer faces 13 and 14near their outerv portions. The ring 11 abuts against the bead 6 at oneside of the tire cover, and

the ring 12 bears against the opposite 'side of the'cover in the usualmanner.

A split locking ring16 is sprung into the depressed groove 5 of the mainrim 3, and s purposed to lock the tire cover and ad Jacent parts inposition. In detail the ring 16 is provided at one end with an inturnedlug l7. Near the extremity of the adjacent end is an oblong recess 19,in which registers a plate 21 resting in the bottom of the groovedflange 5, or integral with said flange. The plate is provided 'with acentral threaded opening 22 to loosely receive a screw 24 which alsotraverses an opening 26 in the flanged seat 5, and.

, ably curved in cross section, and the inner face 30 of the plate 21 iscurved to conform more nearly to its seat.

The normal position of the locking parts is shown in Fig. 3. When it isdesired to remove the locking ring the screw 24 is turned whereby itsouter end elevates the re cessed end of the locking ring 16 to a pointabove the member 5 where 1t is accessible for removal. When the bearingring 12 is provided with an inclined face 14, the latter in conjunctionwith .the elevating screw serves to force the ring 16 outwardly andlaterally to the position indicated in Fig. 8.

What I claim is 1. The combination with a wheel rim, of

a flange upon the rim provided with a longi- I 2. The combination with awheel rim, of.

a flange upon the rim provided with a I oove and with two openings, asplit lockin one "openi ng, a screw loosely mounted in the secondopening and abutting against the other end of the locking ring toelevate the recessed end thereof in position for its easy removal and aplate located between the flange and the last mentioned end and providedwith a threaded opening to receive said screw.

3. The combination with a wheel rim hav-' ing a grooved flange, of aplate seated in ring seated in the groove, a lug upon one end of thelocking ring extending intosaid flange, a bearing ring bearing on saidflange, a locking ring With its ends disconnected and having one endengaged in said flange and the other provided with a longitudinallydisposed recess upon its under face to receive said plate, and a forcingdevice independent of said locking ring and movably mounted in saidplate and engageable with the adjacent end of said ring to elevate thelatter in position for easy removal.

4. The combination with a Wheel rim having a grooved flange, of a plateseated in said flange,a bearing ring bearing on said flange, a lockingring with its ends disconnected and having one end engaged in saidflange and the other provided with a longitudinally disposed recess uponits under face to receive said plate, and a forcing device in dependentof said locking ring and movably mounted in said plate and engageablewith the adjacent end of said ring to elevate the latter in position foreasy removal, the outer face of said bearing ring being outwardly'inclined for outwardly guiding the end of the locking ring as the latteris forced out- Ward.

In testimony whereof I have afiiXed my signature in presence of twoWitnesses.
